D10P
PASSIVE DIRECT INJECTION BOX
Thank you for choosing a PROEL product.
IMPORTANT: read all the safety instructions that
appear at the end of this document.
All PROEL products are CE approved and designed for
continuous use in professional applications.
DI Boxes perform several important functions: they are
designed for impedance matching and balancing the signal
of a guitar, a keyboard or any line-level output source, and
for injecting directly the signal with very long connections to
the XLR microphone inputs of a mixing console.
D10P is a passive direct box with transformer and does not
require any external power such as phantom power or
batteries to work.
The advantage of a transformer is the possibility to avoid any
electrical connection between the sound source and the
mixer. This provides two huge benefits: with no electrical
path, ground loops are eliminated and the cancellation of
common-mode noise, like hum, is possible.
